Accumulation of Vitrified Embryos Followed by Frozen Embryo Transfer in Poor Ovarian Responders According to Bologna Criteria
Background: The aim of current study is to compare the pregnancy outcome between natural cycle IVF-ET (NC group) and frozen ET following accumulation of vitrified embryos (ACC-E group). Methods: The ACC-E group included 38 frozen ETs in 30 patients and the NC group included 92 natural or modified IVF-ET cycles in 91 patients. In the ACC-E group, natural cycle or modified natural cycle with mini...
متن کاملObstetric outcomes after transfer of vitrified blastocysts.
BACKGROUND It has been claimed that the risks to the child resulting from vitrification as compared with the slow-freezing technique, may be higher owing to the high concentrations of potentially toxic cryoprotectants. We therefore retrospectively compared the obstetric and neonatal outcomes in a cohort of children born after transfer of vitrified blastocysts, fresh blastocysts and slow-frozen ...
متن کاملP-42: Who Owns the Frozen Embryos?
Background: Success in assisted reproductive techniques is raising hope for many infertile couples, but as in these techniques many embryos are made, there is no choice other than cryopreservation of the not-transferred embryos. Along with development of these techniques, the number of In-vitro made embryos is rising and the number of transferred embryos is decreasing to prevent multiple gestat...
متن کاملEffect of day 3 embryo morphometrics and morphokinetics on survival and implantation after slow freezing-thawing and after vitrification-warming: a retrospective cohort study
BACKGROUND Morphometric and morphokinetic evaluation of in vitro cultured human embryos allows evaluation without time restriction and reduces intra- and inter-observer variability. Even though these technologies have been reported to improve the quality of cleavage stage embryo evaluation during fresh culture, possible advantages in the evaluation of cryopreserved embryos have been scarcely ex...
متن کاملStudy of vitrified, unstained frozen tissue sections by cryoimmunoelectron microscopy.
We describe the development and application of a novel approach to high-resolution ultrastructural analysis of cells and tissues. It is based on the preparation of ultrathin frozen sections of fixed tissues, rinsing of the sections, followed by their embedding on the grid in a layer of vitrified ice, and direct observation with a cryoelectron microscope. Examination of smooth muscle, kidney and...
